CHUTE FOR DREDGlNG-MACHINES.

SPECIFICATION forming part of Letters Patent No. 771,069, datedSeptember 2'7, 1904.

Application filed May 25, 1904.

To all whom. it natty concern.-

Be it known that 1, MICHAEL H ERRON, a citi- Zen of the United States,residing at Bordentown, Burlington county, State of New J ersey, haveinvented a new and useful Improvement in Chutes for Dredging-Machines,of which the following is a specification.

My invention relates to delivery-chutes for dredging-machines.

It comprises means for laterally adjusting the chute, so that it maydeliver at difierent points in the body of the scow.

It further consists of novel features of construction, all as will behereinafter fully set forth.

My present invention is an improvement over that granted to me February19, 1889, No. 397,985, for an extension-chute, which was, however,incapable of lateral movement.

Figure 1 represents a partial elevation and partial sectional view ofthe device embodying my invention. Fig. 2 is a fragmentary 'plan view ofthe chute, showing its different positions.-

1 designates the deck of a dredge provided with an elevator of anydesired form, shown as an endless chain carrying a plurality of buckets2. From the deck 1 rises a mast 3, having a gaff 4 pivoted on a bolt 5at its upper end. A brace 6 is secured at its outer end by a strap 7 tothe gaff 4 and has at its inner end a throat-strap 8, bearing on acollar 9, suitably secured on the mast 3. Between the mast 3 and theedge of the dredge is a post 10, shown as in two parts united by a head11. Secured to the mast 3 and post 10 is a main chute 12, adapted toreceive the mud or earth from the buckets 2, as shown by the arrow inFig. 1. Adjacent the post 10 and between the post and the edge of thedeck is a column 13, pivotally mounted in the upper end of which is achute extension 14:- From the extension M extends outwardly and upwardlya pair of arms 15, to the outer end of which is pivoted a yoke 16,carrying a second chute extension 17. In like manner arms 18 on theextension 17 carry a yoke 19, supporting a third extension-piece 20.Other extension-sections, 21 and 22, are similarly supported, as shownin Fig. 1. From Qerial No. 209,662. (No model.)

eyes at the outboard ends of each of the extension-chutes 17, 20, and 21chains 23, 24:, and 25 pass to. an eye at the head 11 of the post 10.'From the outboard end of the last extension 22 a chain 26 rises, passingover idlers 27 28 at the ends of the gaff 4L and downward to a winch,(not shown,) which may be of any desired form. I

The operation is as follows: l/Vhen it is desired to deposit the mud orearth raised by the buckets 2 at the side of a scow 29 farthest from thedredge 1, the parts of the device are set as shown in Fig. 1 of thedrawings. It is obvious that the earth will pass through the main chute12 and through the extensionchutes 14, 17, 20, and 22 and drop into thescow, as shown by the arrows, Fig. 1. hen it is desired to fill the sideof the scow nearer the dredge, the extension-chutes 17, 20, 21, and 22are successively raised, by means of the chain 26, to the position shownin dotted lines, Fig. 1. It is evident that in this case the earth willpass through the chutes 12 and 14: and drop as shown by the dotted arrowin Fig. 1. It is evident that to deposit the earth midships of the scow29 the outer sections 21 and 22 of the chute are hoisted by means of thechain 26, leaving the sections 17 and 19 in their operative position.The device thus far described is in many respects similar to that shownin my former patent above named. In practice, however, it is found thatthe labor and expense of shifting the scow alongside of the dredge isconsiderable, this shifting being required in my old device to depositthe earth fore and aft of the scow. With small scows this shifting issometimes done by hand; but with the large scows now in use it isnecessary to keep a tug in almost constant attendance on the scow toshift her as required. To overcome this difficulty, I have pivoted theinboard extension-chute 1 1 on-the column 13 and hung the entireextension part of the chute from the chain 26, secured at its outer endand running to a pivoted gaff 4. As clearly shown in dotted lines, Fig.2, the extension-chute may be swung bodily either directly fore or aftof the scow or at an angle with its sides. The earth from the main chute12 will always drop into the extension M and will be conveyed thencethrough all or some of the sections 17, 20, 21, and 22 to the desiredpoint, it being of course obvious that one or more of the outer sectionsmay be successively raised by means of the chain 26 without regard tothe direction in which the extension-chute may at the time be pointing.It will be seen that by the combination of the successively-raisedsections and of the swinging chute I am able to cover practically everypoint of the scow, so as to deliver the load in a very even mannerwithout producing any strain and without shifting the scow.

It is evident that various changes may be made by those skilled in theart which may come within the scope of my invention, and I do not,therefore, desire to be limited in every instance to the exactconstruction herein shown and described.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A delivery-chute comprising a main section, a plurality of sectionscomposing a second section forming an extension of said main section andoperatively connected therewith, and independent pivotally-mounted meansfor supporting said second section, whereby it may be laterallydeflected.

2. A delivery-chute comprising a main section, a plurality of sectionsforming an extension of said main section and operatively connectedtherewith, and independent pivotally-mounted and vertically-adjustablemeans for supporting said extension, whereby it may be laterally andvertically deflected.

3. A delivery-chute comprising a main section, a plurality oflongitudinally-connected sections forming an extension of said main 4section and 'operatively connected therewith, and separatepivotally-mounted means for supporting the inboard and outboard ends ofsaid extension, whereby it may be laterally deflected.

4. A delivery-chute comprising a main section, a plurality oflongitudinally-connected sections forming an extension of said mainsection and operatively connected therewith, and separatepivotally-mounted means for supporting and vertically adjusting theinboard and outboard ends of said extension, whereby it may be laterallyand vertically deflected.

5. A delivery-chute comprising a main section, a mast, a gafi pivotallyconnected with said mast and a plurality of longitudinallyconnectedsections operatively connected to said main section and forming anextension thereof, the inner of said extension-sections being pivotallysupported, the outer of said sections being supported from saidgafl,whereby they may be laterally deflected.

6. A delivery-chute comprising a main section, a mast, a gafl pivotallyconnected with said mast, a plurality of longitudinally-connectedsections operatively connected With said main section and forming anextension thereof. the inner of said extension-sections being pivotallysupported and the outer of said sections being supported from said gafland guy-chains connected to certain of said extension-sections, wherebysaid extension may be laterally and vertically deflected.
